Assumptions: This post assumes the reader understands the following: Motivation and Preliminary Information to understanding Tensor Products: In math and physics, we often want to represent two vector spaces as one. This, for example, is the case in quantum mechanics when we want to represent the Hilbert space of two individual systems as one combined…

Assumptions: This article assumes the reader has basic knowledge of the following concepts: Introduction and Motivation to Partial Trace: Often in information theory, we have a composite system. That is, we have a system of the form: and we want to know about system A only. This goal is the motivation for a partial trace…
